This invention relates to radiators and more especially to an improvedcompound cooling radiator,.-havingparticular utility in connection *with fiuid compressors and with compressor and internal combustion engine combinations; althoughlt is not limlted to a particular use or purpose butmay he employed wherever 'found desirable.

ator inthe water or other cooling fluid circuit and an entirely separate cooler for cooling the compressed air or other fluid.

The object of thepresent invention is to provide a common-radiator forthe working and cooling of other fluids and a compact and effective compound radiator construction that maybe economically produced and Fig. 2 is an grammatic rearelevational .view of the in which the air andwaterwill beintimately associated in their passage through the radiator. The connections and amount of space required for the radlatormeans are reduced anda .generally improved and unitary c'ooling system for: the air and water or-other fluids isp'rovided. 1 f

To" acquaint those skilled in the art with the mannerot constructing and. practicing the invention, I i shall now describeza particular embodiment of the invention in connection with the accompanyingdrawings in which: Y

The coolingjacket means of the compressor 8 is shown at 10, as surrounding the cylinders 12 of the compressor;

' The particular type and structure of the.

Heretoengine 5,55 well as the particular type j structure ofthe compressor 8 are immaterial and may vary as may the cooling orwater jacket means thereof. The engine 5 maybe omitted and the compressor 8 driven by any other suitable means sofar as. the present invention is concerned. l i

The radiator is shown at also as-mount- *edwith the engine 5 andcompressor 8 upon,

the common base 9, althoughthis may vary as desired. It comprises the upper water box or'lieader 18, the lower water box or header 19, the side members 20,21 andthe compound core structuresQQ and23. i The core structures while preferably of the tubular type may be of the tubular or cellularor any other desired type. The upper water box 18 is provided with theiusual fillercap24and i water intake connection 25. 'The lower water box 19 has a suitablewater outletconnec tion28. 5 The-upper header 18 connects the upper ends ofthe core tubes or vertical water passages through the core structure 22 and also theupperends of thecoretubesor vertical air passages oitheCore or cooler'structure 23.1 The wa'll 30in the upperflbox or header18 is turnedup at 32 to former pocket orcompartment 34which connects the upper ends of the air passages through the cooler and atthe, same timeseparatesthe upper ends of the air passages through the cooler from the upperends of the water passages through the core 22. The box 18 has a compressed air outlet compartment 34.

The lower header similarly connects lower en'dsof the core tubesor vertical water passages through the core structure 22 and also the lower ends of the core tubes or vertical air passages of the core or cooler structure 23. p The wallor partition38 in the lower 3 5 which opensgfrom the i box 19 is turned down at lO-toform a pocket J ends of'the air passages throughthe cooler 23 and at the same time separates thelower ends of the air passages through the cooler23 from air inlet which opens into the compartment or pocket 42.

In the system shown, the jacket means 6 of the engine opens into the outlet manifold 46 which is connected through a conduit or connection 48 with the inlet 25 to the water space of the upper header 18. The jac ret means 10 of the compressor 8 opens into an outlet manifold 50 which may be connected thru the conduit 48 with the water space of the box 18. To thermally control the cool ing effect on the engine without affecting the cooling effect upon the compressor, a thermally controlled valve 52 may be interposed in the conduit 48 between the connections of the manifolds 46 and 50, respectively, therewith, as more fully disclosed in the copending application of myself and Floyd B. Peterson, Serial No. 87,572, filed February 11,1926.

From the core 22 of the radiator 15 the water or other cooling medium is returned through the outlet connection 28 and conduit 56 to the jackets of the compressor 8 and engine 5 through the manifolds 57 and 58 respectively. It will be understood that where the engine 5 is omitted the cooling acket 10 of the compressor 8 only may be connected to the upper and lower water spaces of the radiator 15.

A pump is more or less diagrammatically illustrated at 60 for circulating the cooling medium through the system and a fan 62 is shown as included in the equipment for drawing the air through the water core 22 and cooler core 23 of the radiator.

The compressed air or other fluid or medium is delivered from the compressor 8 through a conduit 63 to the bottom of the cooler 23 through the compressed air inlet connection 45. The compressed air is delivered from the top of the cooler 23 through the outlet connection 35 and a conduit 65 to a reservoir or any other desired point of delivery. The section 28 of the radiator core may have suitable side members and 72.

From the foregoing it will now be apparent that the radiator 15 constitutes a common radiator for the cooling and working fluids of the compressor. The headers 18 and 19 form common headers for and structurally unite the opposite ends of the water and cooler cores and the headers form common fluid connections for the ends of the water and cooler cores and at the same time maintain the cooling and working fluids separated. The arrangement is compact and effective. The amount of space and connections are reduced and the water and air are closely associated and a compact, simple and inexpensive system provided.

I claim:

1. In a radiator, the combination of a pair of separate core structures, a single pair of headers common to both said core structures,

said core structures having passages between said headers, said headers each having separate compartments connecting the passages of one core structure with each other, and the passages of the other core structure with each other, and separating the passages of the two core structures, a pair of inlet connections on one header for the two compartments thereof, and a pair of outlet connections on the other header, one for each of its compartments.

2. In combination, an air cooler, a core structure separated centrally to receive the air cooler and disposed on opposite sides of the air cooler, a pair of headers each common to the air cooler and to said core, the air cooler and core each having passages between the headers, and said headers each having separate compartments connecting the passages of the air cooler with each other, and the passages of the core with each other, and separating the air cooler passages from the core passages.

3. In combination, an air cooler, a core structure separated centrally to receive the air cooler and disposed on opposite sides of the air cooler, a pair of headers each common to the air cooler and to said core, the air cooler and core each having passages between the headers, andsaid headers each having separate compartments connecting the passages of the air cooler with each other, and the passages of the core with each other and separate inlet and outlet connections through the headers for the air cooler and core structures.

4. In a radiator, the combination of a pair of separate core structures, a single upper header joining the upper ends of and common to both said core structures, a single lower header joining the lower ends and common to both said core structures, means in each of said headers separating the passages of the two core structures from each other, inlet and outlet connections for and in communication with one core structure, one with the upper header and the other with the lower header, and inlet and outlet connections for and in communication with the other core structure, one with the upper header and the other with the lower header.

5. In a radiator, the combination of a pair of separate core structures, separate inlet and outlet connections for each core structure, a single header joining the upper ends of and common'to both said core structures and hav ing two chambers therein, one for each core, a second single header joining the lower ends of and common to both said core structures, and having two chambers therein, one for each core.

In witness whereof, I hereunto subscribe my name this 12th day of August, 1926.
